493321 ÷ 45 
We want to figure out the number of times 493321 can be divided by 45.

Advancing to step 1:
If we divide 4 by 45, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 45

Going ahead to step 2:
If we divide 49 by 45, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 45 from 49 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 45

On to step 3:
45 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 43 after subtracting 0 from 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 45

Step 4:
If we divide 433 by 45, we get 9 and a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Subtracting 405 from 433 leaves us with 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 45

On to step 5:
282 divided by 45 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 1096.0
The remainder is 12 after subtracting 270 from 282.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 45

Moving on to step 6:
The number 45 fits into 121 2 times, leaving a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 10962.0
Subtracting 90 from 121 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
The number 45 fits into 310 6 times, leaving a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 10962.6
The remainder is 40 after subtracting 270 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
The number 45 fits into 400 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 10962.68
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
When dividing 400 by 45, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 10962.688
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 10962.688 and a remainder of 0.004.
